Signature of the atmospheric asymmetries of hot and ultra-hot Jupiters in lightcurves
Aurélien Falco, Jérémy Leconte, Alexandre Mechineau +1
With the new generation of space telescopes such as the James Webb Space Telescope (JWST), it is possible to better characterize the atmospheres of exoplanets. The atmospheres of H…
ARES VI: Viability of one-dimensional retrieval models for transmission spectroscopy characterization of exo-atmospheres in the era of JWST and Ariel
Adam Yassin Jaziri, William Pluriel, Andrea Bocchieri +10
Observed exoplanet transit spectra are usually retrieved using 1D models to determine atmospheric composition while planetary atmospheres are 3D. With the JWST and future space tel…
ATMOSPHERIX: II- Characterising exoplanet atmospheres through transmission spectroscopy with SPIRou
F. Debras, B. Klein, J. -F. Donati +26
In a companion paper, we introduced a publicly-available pipeline to characterise exoplanet atmospheres through high-resolution spectroscopy. In this paper, we use this pipeline to…
ATMOSPHERIX: I- An open source high resolution transmission spectroscopy pipeline for exoplanets atmospheres with SPIRou
B. Klein, F. Debras, J. -F. Donati +28
Atmospheric characterisation of exoplanets from the ground is an actively growing field of research. In this context we have created the ATMOSPHERIX consortium: a research project…
Hot exoplanetary atmospheres in 3D
William Pluriel
Hot giant exoplanets are very exotic objects with no equivalent in the Solar System that allow us to study the behavior of atmospheres under extreme conditions. Their thermal and c…
Detecting HO with CRIRES+: the case of WASP-20b
M. C. Maimone, M. Brogi, A. Chiavassa +5
Infrared spectroscopy over a wide spectral range and at the highest resolving powers (R>70 000) has proved to be one of the leading technique to unveil the atmospheric composition…
Toward a multidimensional analysis of transmission spectroscopy. Part III: Modelling 2D effects in retrievals with TauREx
Tiziano Zingales, Aurélien Falco, William Pluriel +1
New-generation spectrographs dedicated to the study of exoplanetary atmospheres require a high accuracy in the atmospheric models to better interpret the input spectra. Thanks to s…
Toward a multidimensional analysis of transmission spectroscopy. Part I: Computation of transmission spectra using a 1D, 2D, or 3D atmosphere structure
Aurélien Falco, Tiziano Zingales, William Pluriel +1
Considering the relatively high precision that will be reached by future observatories, it has recently become clear that one dimensional (1D) atmospheric models, in which the atmo…
Towards multi-dimensional analysis of transmission spectroscopy. Part II: Day-night induced biases in retrievals from hot to ultra-hot Jupiters
William Pluriel, Jeremy Leconte, Vivien Parmentier +4
Hot Jupiters are very good targets for transmission spectroscopy analysis. Their atmospheres have a large scale height implying a high signal to noise ratio. As these planets orbit…
ARES V: No Evidence For Molecular Absorption in the HST WFC3 Spectrum of GJ 1132 b
Lorenzo V. Mugnai, Darius Modirrousta-Galian, Billy Edwards +25
We present a study on the spatially scanned spectroscopic observations of the transit of GJ 1132 b, a warm (500 K) Super-Earth (1.13 R) that was obtained with the G1…
ARES IV: Probing the atmospheres of the two warm small planets HD 106315 c and HD 3167 c with the HST/WFC3 camera
Gloria Guilluy, Amélie Gressier, Sam Wright +27
We present an atmospheric characterization study of two medium sized planets bracketing the radius of Neptune: HD 106315 c (R=4.98 0.23 R) and HD 3167 c…
ARES III: Unveiling the Two Faces of KELT-7 b with HST WFC3
William Pluriel, Niall Whiteford, Billy Edwards +24
We present the analysis of the hot-Jupiter KELT-7b using transmission and emission spectroscopy from the Hubble Space Telescope (HST), both taken with the Wide Field Camera 3 (WFC3…
ARES II: Characterising the Hot Jupiters WASP-127 b, WASP-79 b and WASP-62 b with HST
Nour Skaf, Michelle Fabienne Bieger, Billy Edwards +24
This paper presents the atmospheric characterisation of three large, gaseous planets: WASP-127b, WASP-79b and WASP-62b. We analysed spectroscopic data obtained with the G141 grism…
ARES I: WASP-76 b, A Tale of Two HST Spectra
Billy Edwards, Quentin Changeat, Robin Baeyens +25
We analyse the transmission and emission spectra of the ultra-hot Jupiter WASP-76b, observed with the G141 grism of the Hubble Space Telescope's Wide Field Camera 3 (WFC3). We redu…
Strong biases in retrieved atmospheric composition caused by strong day-night chemical heterogeneities
William Pluriel, Tiziano Zingales, Jérémy Leconte +1
Most planets currently amenable to transit spectroscopy are close enough to their host star to exhibit a relatively strong day to night temperature gradient. For hot planets, this…
Modeling the albedo of Earth-like magma ocean planets with H2O-CO2 atmospheres
William Pluriel, Emmanuel Marcq, Martin Turbet
During accretion, the young rocky planets are so hot that they become endowed with a magma ocean. From that moment, the mantle convective thermal flux control the cooling of the pl…
